Workshop: Electronics From Scratch is Easy - a Nottingham Hackspace geek's introduction to electronics and why you can do it!

Many a geek has come to electronics late and thinks that there's just a bit that he/she doesn't get. The subject appears "hard". Why isn't it straightforward like software? Well, the good news is that it IS straightforward and all that is needed is a particular way of looking at things.

This stuff just works but why? An inquisitive mind.

  • Electromagnetic phenomena
  • electrical charge - electrons!
  • static electricity - making it, storing it, using it!
  • a galvanometer!
  • current - the flow of electrons
  • conductivity
  • electrical potential and voltage

The physics and mathematics of electromagnetic flux with Lorentz and Maxwell's equations (and why you can immediately forget this!)

  • Lumped Matter Discipline
    • we use components!
    • Open the black box - take a look - close it forever!
    • as long as we treat these things nicely, everything will work!
    • play, fail, try again!
  • resistance to current flow - resistors
  • storage of charge - capacitors
  • other forms of impedance and inductance (conversely, reactance!)
  • silicon semiconductors - a diode!
  • valves
  • bipolar transistors
  • building neat things
  • logic circuits
  • bigger and bigger systems
  • ICs
  • microcontrollers/SOCs/computers
  • ferrite core memory
  • supercomputers!
  • ?????
  • world domination!
